Selection for production and reproduction in South African Merino sheep is always combined with selection based on visual appraisal and will, in all probability, remain so for many years to come. Heritabilities for acceptability were estimated using a threshold model…
Heritability estimates and breeding value predictions of Dormer sires for litter size and lamb mortality were obtained using a threshold model. Heritability estimates on the underlying scale were 0.24 and 0.12 for litter size and mortality, respec¬tively. Breeding value predictions…
The objective of this study was to estimate heritability and breeding values on theunderlying scale for different reproductive traits and survival rate in Afrino sheep to ascertain whether they can be improved by selection on estimated breeding values obtained under…
